The light emitting diodes pass through the layout of the printed circuit on the bottom face of the circuit board, and the light emitting diodes are connected with a power plug by dint of a power supply line. The beehive-shaped grating matches with the figure of the circuit board and is positioned in front of the throw light of the light emitting diodes. The sealing closure of the locking closure is provided with the opening and matches with a plurality of the screw locks for propping up the waterproof washer ; thus the waterproof effect can be obtained.

Description

Portable lamp

[technical field]

The utility model relates to a kind of light fixture, particularly relates to a kind of low power consumption, no temperature-rise effect and can improve the portable lamp in service life.

[background technology]

Generally such as NC, CNC lathe, drilling machine, reach machining machine and tools such as comprehensive machine, all install lighting based on requirements of one's work at the cutter Working position, carrying out in order to processing, but, the general light fixture that uses adds the liquid splashes such as liquid, cutting fluid that are cooled easily man-hour at facility, make and place inner circuit because of water short circuit, damage, so the facility of this class all can use more special watertight light fitting to avoid above-mentioned situation, therefore, watertight light fitting is used on the toolroom machine, and is more and more general and be subjected to liking of each industry.

At No. the 349630th, Taiwan patent announcement, No. 454852, bulletin, and bulletin patent case such as No. 493719 has all disclosed a kind of work light fixture of waterproof, the bulb of work light fixture is to adopt general bulb to cooperate the optically focused dish to come throw light, and the acquisition illuminating effect, yet there are following two defectives in this bulb: first temperature rise is fast, power consumption is big, service life is short; It two is that this bulb all adopts materials such as fluorescent lamp, neon lamp, quartz lamp, and after this bulb went out of use, there was environmental issue in materials such as halogen wherein, quartz glass, therefore, at above-mentioned disappearance, the necessity that is improved were again arranged really.

[utility model content]

The purpose of this utility model is to provide a kind of low power consumption, no temperature-rise effect, and can improve service life, and environment friendly and pollution-free portable lamp.

Portable lamp of the present utility model includes a lamp housing main body, a circuit substrate, a honeycomb-type grating, a glass, a waterproof washer, and a locking closure, it is characterized in that:

The lamp housing main body has a hollow lampshade, from will covering outward extending support, and a joint chair that is formed at the support bottom, and this lampshade is provided with an opening.

Circuit substrate is installed in lampshade inside, and in the end face proper alignment numerous light emitting diodes is arranged, and light emitting diode borrows a power line to be connected to attaching plug through the printed circuit layout of circuit substrate bottom surface.

Honeycomb-type grating is installed in lampshade inside, and cooperates the profile of circuit substrate to be placed in the place, the place ahead of light emitting diode throw light, to reduce the sidelight situation.

Glass is installed in lampshade inside, and is blocked in honeycomb-type grating the place ahead.

Waterproof washer is installed in the groove of lampshade.

Locking closure is used for the opening of capping lampshade, and cooperates some screw locks to be against on the waterproof washer, to obtain waterproof effect.

[description of drawings]

Below by most preferred embodiment and accompanying drawing portable lamp of the present utility model is elaborated, in the accompanying drawing:

Fig. 1 is a three-dimensional exploded view, and the most preferred embodiment of portable lamp of the present utility model is described.

Fig. 2 is a side-looking part sectioned view.

Fig. 3 is a front view, and the arrangement situation of a honeycomb-type grating and some light emitting diodes is described.

[specific embodiment]

Consult Fig. 1, Fig. 2, the most preferred embodiment of the utility model portable lamp, comprise a lamp housing main body 1, a circuit substrate 2, numerous light emitting diode 3, a honeycomb-type grating 4, a glass 5, a waterproof washer 6, a locking closure 7, several screws 8, and some C shape banking stops 9.

Lamp housing main body 1 has a hollow lampshade 11, a support 12, from lampshade 11 outward extending adjustable angles to be formed at joint chair 13, an attaching plug 14 of support 12 bottoms, and one is placed in lampshade 11 outer surfaces and is electrically connected at circuit substrate 2 and the change-over switch 15 of 3 of light emitting diodes.Lampshade 11 has an opening 111, some grooves 112 that are formed on opening 111 inboards, and C shape banking stop 9 cooperates circuit substrate 2, honeycomb-type grating 4, and the erection sequence that reaches glass 5 is embedded in groove 112 inside from inside to outside one by one, to reach position-limiting action.

Light emitting diode 3 is a kind of high brightness LED.

Circuit substrate 2 is installed in 112 of two grooves of lampshade 11 inside, and being subjected to two, to be embedded in 9 of the C shape banking stops of groove 112 spacing, light emitting diode 3 proper alignment are at its end face, and the printed circuit layout of process circuit substrate 2 bottom surfaces, and borrow a power line 10 to be connected to attaching plug 14.

Consult Fig. 2, Fig. 3, honeycomb-type grating 4 is installed in lampshade 11 inside, and cooperates the profile of circuit substrate 2 to be placed in the place, the place ahead of light emitting diode 3 throw lights, to reduce the sidelight situation.

Consult Fig. 1, Fig. 2, glass 5 is installed in lampshade 11 inside, and is blocked in honeycomb-type grating 4 the place aheads.

Waterproof washer 6 is placed in glass 5 outsides.

Locking closure 7 is sealed on opening 111 places of lampshade 11, and cooperates screw 8 to compress waterproof washer 6 and locking on lampshade 11, to obtain waterproof effect.

Portable lamp of the present utility model, connect with the mains change-over switch 15 when being in switching position at attaching plug 14, can light light emitting diode 3 immediately, because the utility model has adopted high brightness LED 3, so light luminance is pure, best illuminating effect and application target can be provided, and because honeycomb-type grating 4 is placed in the place ahead of light emitting diode 3 throw lights, light can be concentrated towards the place ahead, be difficult for producing the situation of sidelight, so have the effect of optically focused concurrently.Add the design of waterproof washer 6, make this portable lamp possess the effect of waterproof.

In addition, the utility model voltage, power are not limit, therefore can be on demand, and with the quantity of light emitting diode, the circuit design of the suitable watt/power of collocation is used.

Via above-mentioned explanation, portable lamp of the present utility model has following effect and advantage in fact:

One, the utility model adopts high brightness luminescent diode 3, and not only light does not have temperature rise enough, fully Effect, so stability is high and can promote service life, and light emitting diode 3 has low power consumption, And after discarded free of contamination advantage, have more power saving and meet environmental protection function etc. and use requirement.

Two, be placed in the place ahead of light emitting diode 3 throw lights by honeycomb-type grating 4, have Optically focused effect, and anti-sidelight effect, therefore, the irradiation mode of this portable lamp is direct irradiation, Result of use will be brighter.
