Description
ROBERT BOSCH GMBH; D-70442 Stuttgart Device comprising a plastics
component and a light-emitting diode.
The prior art
The invention is based on a device comprising a plastics component and a light-emitting diode (hereinafter also called a LED) according to the preamble of claim 1.
It has already been proposed to combine a plastics component with a LED, for example, for manufacturing a LED display. In this case the LED is soldered to a circuit board to which conductive tracks are applied, and covered after soldering with a viewing pane for protection.
Advantages of the invention The invention is based on a device comprising a plastics component and a light-emitting diode.
It is proposed that the LED be cast into the plastics component. A robust unit in which the LED is retained in the plastics component by a material joint so that it cannot be lost and is resistant to mechanical damage can thereby be obtained. In particular, a separate assembly step for installing the LED can advantageously be dispensed with during final assembly. In addition, a multiplicity of LEDs may, in particular, be cast together to form a robust unit. By casting-in the LED, a plastics component which has L\.
an illumination function and is especially shock-resistant can be produced.
In this context a LED refers to a unit comprising a wired semiconductor chip, conductor terminals and a lens made, for example, of glass or epoxy resin. The range of meanings of the term "cast in" should also include "incorporated by injection moulding". In addition to single-component and multi-component injection moulding processes, artificial- resin casting processes may also be used.
If a plastics material of the plastics component is injected around the LED, an especially secure connection between the LED and the plastics component can be obtained.
In particular, plastics components made of an especially stable high-temperature-resis and/or high-pressure- resistant plastics material can be fitted with LEDs. Low- cost mass production can be achieved and temperature- sensitive and/or brittle adhesives can be dispensed with.
An injection point of an injection mould can advantageously be so selected that an injected plastics melt reaches a region of the conductor terminals under reduced pressure and/or at reduced velocity. Damage to the conductor terminals can thereby be avoided even under high pressures of 600 to 2000 bar and at high temperatures above 200 C.
Embodiments of the invention in which a mould includes means for shielding the conductor terminals from the injected plastics melt are also possible.
As materials for injection, thermoplastics such as acrylonitrilebutadiene_styrene (ABS), polyamide (PA), polycarbonate (PC) and polypropylene (PP) may be considered, and the materials may also contain a short- fibre glass fibre reinforcement. A duroplastic material injection moulding process is also possible.
In a development of the invention it is proposed that the LED includes a lens-like transparent cap. The cap may advantageously shield a conductive connection between the conductor terminals and the semiconductor chip of the LED from the plastics melt. In addition, low-cost standard components made be utiljsed when selecting the LED.
The focusing properties of the lens-like cap may advantageously be utilised if a lens region of the cap projects beyond a surface of the plastics component.
However, a plastics component having focusing properties adapted to a specific application may also be obtained if a lens-shaped region is moulded into the plastics component.
In this context any convex or concave configuration of a surface of the plastics component adapted to the LED in its dimensions and its position and acting like an optical lens is referred to as "lens-like".
Absorption of light from the LED in the plastics component can be at least largely avoided if the plastics component is made of a transparent plastics material.
A robust power supply protected from outside influences, and simple installation in an assembly, can be achieved if the device includes at least one conductive track for supplying current to the LED which is cast into the plastics component. The conductive track may be in the form, for example, of wire or punched sheet metal or may be sprayed or metallised on to a support or applied galvanically thereto.
The advantages with respect to robustness and impact and shock resistance of a device are exploited in particular if the plastics component is a component of a hand-held power tool, and in particular a component of a hand-held power tool housing.
The advantages resulting from ease of assembly, reliability and long service life are especially beneficial if the plastics component is an electronic component of a motor vehicle. In that case the LED may be used especially advantageously as an indicator light which directly informs a user and/or mechanic of the motor vehicle of the correct functioning and/or operating state of an assembly.
Casting-in of high-intensity, high-power LEDs can be made possible if the device includes at least one moulded-in cooling body for cooling the LED. Especially effective heat dissipation can be achieved, for example, by using cooling bodies having metal cooling ribs or heat pipes.
A multiple signalling function of the plastics component can be achieved if at least two different LEDs are cast into the plastics component. The LEDs may have different.
orientations, different colours and/or different light intensities.
Information density can be further increased if the plastics component forms an identifying or signalling element. The plastics component may serve as an information element if, for example, it carries a manufacturer logo and/or a product name. An especially striking effect can be achieved if the LED illuminates the information and/or signalling element.
If the device includes at least one control unit for activating the LED in dependence on an operating state parameter, an operating state of a tool including the plastics component can be made especially clearly detectable visually, and incorrect use in an unsuitable operating state can be avoided.
In this case increased information density can be achieved if the control unit is provided not only to switch the LED on and off permanently but also to activate and deactivate it periodically in at least one operating state, i.e. to activate the LED in a flashing mode.
The drawings Further advantages are apparent from the following description of the drawings. In the drawings embodiments of the invention are represented.

Description of the exemplary embodiments
Fig. 1 shows a plastics component lOa in the form of a component of a hand-held power tool which is produced from acrylonitrile_butadjene_styrene in an injection moulding process. During manufacture of the plastics component lOa a LED l2a is placed in an injection mould and surrounded by a plastics material of the plastics component lOa, so that a material joint between the plastics component lOa and the LED l2a is produced. The LED 12a is thus cast or injectionmoulded into the plastics component lOa.
The LIED 12a includes a semiconductor chip 24a made of a Ill-v semiconductor with a p-doped region and an n-doped region. The semiconductor chip 24a is embedded in a lens- like, transparent cap 14a, which has on its upper surface a convex lens region 16a which is provided to focus light generated by the semiconductor chip 24a. The semiconductor chip 24a is connected via two contacts to conductor terminals 26a, 26a', by means of which an electric current can be conducted through the semiconductor chip 24a.
The lens region 16a projects beyond a surface of the plastics component lOa, so that the latter affects the illumination properties of the LED 12a only marginally.
Figs. 2-9 show further embodiments of the invention. The description is restricted essentially to differences from the embodiment represented in Fig. 1, reference being made to the description of Fig. 1 with regard to features remaining the same. Analogous features are denoted by the same reference numerals, the letters a-i being appended to the numerals to distinguish the embodiments.
Fig. 2 shows a plastics component lOb which is made of a transparent plastics materi.a using an injection-moulding process. Except for conductor terminals 26b, 26b' projecting from an underside of the plastics component lOb, a LED 12b is surrounded by the transparent plastics material. A plastics layer also covers a lens region 16b of the LED l2b, the plastics layer having a further configuration in the lens region 16b to form a lens-like region 18b which focuses light emitted by the LED 12b. As a result of a high refractive index of the transparent plastics material the lens region 16b loses a part of its focusing effect. This is compensated by the lens-like region 18b.
Fig. 3 shows a plastics component lOc in the form of a bus bar which is provided to supply current to an engine component and therefore forms an electronic component of a motor vehicle. The plastics component 10c includes two plug-in contacts 28c, 30c and a plurality of conductive tracks 20c punched from sheet metal in its interior. Prior to insertion in an injection mould, a LED 12c is soldered to the conductive tracks and then surrounded with injected duroplastic material. The material joint produced in this way ensures sealing in the region of the LED 12c and can prevent penetration of engine oil and spray water. The LED l2c may be used as an indicator light for indicating an operating state of the engine component. In further embodiments of the invention the LED 12c may be welded or crimped to the conductive tracks 20c.
Fig. 4 shows a carrier circuit board 32d having a multiplicity of LEDs l2d which are connected via printed conductive tracks 20d to a plug-in contact 30d, via which all the LEDs 12d are supplied with current. After being mounted on the carrier circuit board 32d, the LEDs 12d with the conductive tracks 20d are encapsulated with a transparent plastics material to form a compact assembly. A surface of a plastics component lOd including the carrier circuit board 32d and the LEDs l2d has lens- like, concave
-
regions 18d which act as dispersing lenses. The plastics component lOd is used as an illumination means of a gallery lighting system for illuminating paintings.
Fig. 5 shows a further plastics component lOe analogous to the plastics component lOd, the surface of which includes lens-like convex regions 18e which focus light generated by LEDs 12e to an emission angle of 20 .
Fig. 6 shows a plastics component lOf in the form of a motor vehicle lamp comprising a multiplicity of LEDs 12f- 12f''' . The LEDs 12f-12''' are encapsulated below a curved surface of the plastics component lOf. The surface is subdivided into four zones 34f- 40f: a rear-light zone 34f equipped with red LEDs 12f, a reversing light zone 36f equipped with white LEDs 12f', a direction indicator zone 38f equipped with orange LEDs 12f'' and a brake light zone 40f equipped with red LEDs 12f''' . In a further embodiment of the invention the zones 34f-40f might be encapsulated with different-coloured transparent plastics material in a multi-component injection moulding process.
Fig. 7 shows a portion of a further alternative plastics component lOg in which a LED 12g in the form of a high- power LED and a cooling body 22g for cooling the LED 12g are moulded-jn. The plastics component lOg forms a front region of a hand-held power tool, the LED 12g being provided to illuminate a working area, for example, a drill hole.
Fig. 8 shows a plastics component lOh which is provided to be inserted as a compact assembly in a hand-held power tool housing. Three LEDs 12h12h''are encapsulated in the plastics component lOh and are activated by control electronics of a hand-held power tool which includes the plastics component l0h when a rotational speed exceeds a threshold value allocated to the respective LED 12h-12h'' A width of a triangular mask 42h in the region of the respective LED l2h-12h'' corresponds at least qualitatively to a magnitude of the threshold value allocated to the corresponding LED 12h-12h''. The plastics component can be used flexibly to indicate all the time-variable parameters of the hand-held power tool which appear useful to the person skilled in the art, for example, for displaying and visualising a rotational speed or a torque value.
Fig. 9 shows a further plastics component lOi in the form of a hand-held power tool component including two different encapsulated LEDs 12i, 12i', namely a red LED 12i and a green LED 12i', which are provided for displaying a charge state of a storage battery pack of a hand-held power tool which includes the plastics component lOi. With a sufficiently charged storage battery pack, a control unit of the hand-held power tool activates the green LED 121', whereas with a small residual charge the control unit activates the red LED 12i.
A hand-held power tool 44j illustrated in Fig. 10 includes a housing 46j with a laterally arranged plastics component lOj having four encapsulated LEDs 12j-12j'''. The plastics component lOj illustrated separately in Fig. 11 is made of a transparent plastics material and has on a reverse side a relief-like, coloured identifying and signalling element 48j which is illuminated in operation by the LEDs l2j- 12j'''. The identifying and signalling element 48j forms an image of a manufacturer logo, in particular a picture mark 50j and a script 52j.
The hand-held power tool 44j further includes a control unit 54j for activating the four LEDs 12j-12j''' in dependence on an operating mode of the hand-held power tool 44j. The control unit 54j can either switch on the LEDs 12j-12j''' permanently or switch them off permanently or switch them on and off periodically in a flashing mode, i.e. can cause them to flash. Permanent switching-on signals to an operator a general readiness for operation of the hand-held power tool 44j, while permanent switching-off indicates absence of a power supply to the hand-held power tool 44j.
If the control unit 54j is awaiting an input by the operator, the control unit 54j activates the LEDs l2j- 12j''' in the periodic flashing mode in which the LEDs 12j- 12j''' are switched on and off with a period of 3 sec'.
Such an input may relate, for example, to selection between a clockwise and an anticlockwise mode of rotation of the hand-held power tool 44j. Once the operator has made the input, the control unit 54j switches to the constant illumination mode. In general, the flashing mode is additionally always switched on if the hand-held power tool is executing a process that cannot be influenced from outside. An example of such a process is charging of a storage battery pack 56j of the hand-held power tool 44j.
Fig. 12 shows an alternative hand-held power tool 44k having a transparent plastics component 10k (Fig. 13) which is in the form of a script and which extends from the inside through corresponding openings in a housing 46k of the hand-held power tool 44k. The shape of the plastics component 10k, which is moulded in one piece, is composed of a plurality of letters 58k-58k'''' which are firmly connected together by bridges. The letters 58k-58k'''' are moulded on to a carrier circuit board 32k which has been equipped with LEDs 12k prior to encapsulation. The LEDs 12k are arranged on a contour replicating the letters (Fig. 14) and are encapsulated in the plastics component 10k, so that the LEDS 12k, the carrier circuit board 32k and the letters 58k-58k'''' form a compact assembly.
Fig. 15 shows an alternative carrier circuit board 321 with LEDs 121 in the form of surface-mountable SMD semiconductor components which are soldered directly from the front, without conductor terminals, to a carrier circuit board 321. The carrier circuit board 321 is printed from the front with conductive tracks 201.
The LEDs 12j-121 shown in Figs. 12 to 15 are activated by a control unit 54j, 54k in dependence on operating parameters of the hand-held power tool 44j, 44k.
