The light source component is of a printed circuit board component on which a group of light source pixel dots are welded and a lighting source of each light source pixel dot is a set of a LED. The shell consists of an upper plastic shell and a lower plastic shell which can be interlocked with each other. The utility model is a back light source with environmental friendliness, energy conservation and long service life. The novel structure design of the utility model can effectively improve light brightness and earthquake resistant strength and light more evenly.

Description

New LED line style lamp

Technical field

The utility model relates to a kind of lamp source line that uses as backlight, refers to a kind of New LED line style lamp (Channel Letter) especially.

Background technology

Backlight generally is for display floater provides light source, and in order to ensure the quality of display frame, it should have brightness height, luminous even, performances such as light angle is big, adjustable, high efficiency, low-power consumption, the life-span is long, light and approach.And the generally light sources that adopt of the present line style lamp that uses as backlight are fluorescent lamp, neon light (cold-cathode lamp) more, and light source life is low, and power consumption is generated heat greatly and easily, thereby by the line style lamp source that it constitutes following shortcoming are arranged:

1. luminous brightness irregularities behind the bright lamp;

2. fluorescent tube is generally all long, and stroke weight is not easy to arrange, and is dumb;

3. the fluorescent tube heating is big, causes its lost of life

4. photoelectric efficiency is lower, and power consumption is big, and is not energy-conservation, not environmental protection;

5. fluorescent tube starts needs by electronic starter or ballast, and environment is bigger to its influence.

Led light source is a kind of plane light source, very easily combines the area source that becomes set area, has good brightness uniformity; Have better colour gamut as make backlight of led light source, color representation power is better than the cold-cathode lamp backlight; And long service life, use be the low-tension supply of 5～24V, fool proof; Anti-seismic performance is outstanding, adds that LED does not need to use environmentally harmful mercury metal, environmental protection more.Because the various advantageous characteristic that led light source has have now begun to develop with its use as backlight, utilizing future led light source to do backlight will be an expected developing direction.

But the luminosity of led light source is still waiting to improve at present.

Summary of the invention

The purpose of this utility model provides a kind of environmental protection, energy-conservation, long-life backlight New LED line style lamp, adopts novel structural design can effectively improve luminosity and shock strength, and is luminous more even.

For achieving the above object, the utility model is taked following design:

A kind of new LED line style lamp, comprise the lamp source component and encapsulate the shell of this lamp source component, described lamp source component is PCB (Printed Circuit Board) assembly, and it adopts one group of lamp source image vegetarian refreshments of welding on the pcb board, and the light emitting source of each lamp source image vegetarian refreshments is one group of LED.

Constitute a lamp source image vegetarian refreshments by 5 one group LED.

Described shell is made of interlockable upper and lower plastic casing.

The utility model has the advantages that:

1) adopts light emitting diode (LED) as light source, do not damage photographed object;

2) the cold light source LED life-span longer, fault rate is low;

3) low-power consumption, conservation of power, the later stage uses, maintenance cost is lower;

4) can be according to using needs to select the LED of different colours to do light source;

5) it is more flexible to use, arrange, and it is little or the font of turning round arranged especially to be fit to stroke;

6) use operating voltage to be constant voltage, also relatively flexibly, input voltage can be 12VDC to voltage range, and 24VDC is convenient to client and is selected, and reduces the investment of later stage transformation;

7) UL flame retardant plastics shell design is also done waterproofing design (using casting glue that circuit and device portions are carried out whole encapsulation process, to reach waterproof effect) to circuit and device portions, can use for a long time out of doors, normal.

The specific embodiment

Shown in Fig. 1-a, Fig. 1-b, the utility model LED line style lamp comprises lamp source component 3 and encapsulates the shell (upper casing 1, lower casing 2) of this lamp source component.

The lamp source component of the utility model LED line style lamp is that (the PCB assembly comprises pcb board, LED301, resistance, power line 302 to PCB (Printed Circuit Board) assembly, annexation between it is a prior art, do not give unnecessary details) herein, it adopts one group of (more than 1) lamp source image vegetarian refreshments of welding on the pcb board, and the light emitting source of each lamp source image vegetarian refreshments is one group of LED301.Constitute a PCB assembly by two lamp source image vegetarian refreshments in Fig. 1-c illustrated embodiment, and each lamp source image vegetarian refreshments is made of one group of (5) LED, in the present embodiment, 5 LED put one, serve as that the equidistant mode that evenly distributes four of axle is arranged with the central point with central point.Adopt 5 optical designs that LED is a pixel, can make the light shape complementation of lamp like this, satisfy luminous effect of uniform, and pel spacing can be the lighting angle decision that reaches LED itself by experiment.

The shell of the utility model LED line style lamp is made of interlockable upper and lower plastic casing, has the tapered end 201 of one group of evagination referring to Fig. 1-d, Fig. 2-d, Fig. 3-d lower casing, and the upper casing corresponding position has the locked groove 101 of one group of indent.

The described shell structure of going up can have corresponding elliptical hole 102, for ccontaining LED lamp referring to Fig. 2-a to Fig. 2-d on the top panel.

It is described that shell structure can be referring to Fig. 3-a to Fig. 3-d down.

Outer convex surface of the tapered end that following plastic casing has and longitudinal axis angle are 25～35 ° is advisable, and 30 ° better.The locked groove inner concave of upper casing corresponding position matches (referring to Fig. 2-d, Fig. 3-d).

When the utility model LED line style lamp is made: weld the PCB assembly earlier, after welding finishes, pack into and be fixed in lower casing 2 the insides, casting glue is injected lower casing, cover the PCB assembly fully, treat adhesive curing after, with upper shell cover on lower casing, press shell and make its distortion, the tapered end that lower casing is had inserts the interior interlocking of locked groove of upper casing indent.

According to used LED angle and the isoparametric difference of brightness, can produce the novel line style lamp (Channel Letter) of different-effect, can satisfy the service condition that various varying environments require.

We also can make corresponding particular design according to client's specific (special) requirements, constitute the variation of the LED number of same pixel, the variation of mutual spacing as described; Constitute the variation of same pixel led color, can be homochromy or not homochromy LED.
